For a while its been puzzling me why connman-gnome rebuilds as often as it
does. It turns out you can trigger this with a new checkout of the metadata.
The SRC_URI that is causing the problems is:
SRC_URI = "file://images/*"
and rather oddly the results in checksums for a file "." being added to
the tree, e.g.:
('.', 'ab48a68186f0e0f277c21ef4cb390b4b')
The problem is that when iterating files lists, the checksum variable can
become set yet we don't break the out from the for loop, which leads to
odd (and non-deterministic) entries being added into the file checksum list.
The exact item added probably depends on the order of items on the disk.
Before this change, bitbake-diffsigs on connman-gnome:do_fetch would report:
This task depends on the checksums of files: [
('connman-signal-03.png', 'f6c16aee57b37b73793a2f1dea433ffa'),

('.', 'ab48a68186f0e0f277c21ef4cb390b4b')]
Afterwards:
This task depends on the checksums of files: [
('connman-signal-03.png', 'f6c16aee57b37b73793a2f1dea433ffa'),
('connman-signal-02.png', 'ad0cd22710c097d8174121fc1023c3be'),

('0001-Removed-icon-from-connman-gnome-about-applet.patch', 'e2d8269357c1e8c84291606da24eea85'),
('0001-Removed-icon-from-connman-gnome-about-applet.patch', 'e2d8269357c1e8c84291606da24eea85')]
which is correct and deterministic without the "." entry.
